More on eCampus Quizzes
• There are free warm-up quizzes before the End-of-Chapter
quizzes
– Need a 100% on them (don’t worry… they are easy)
• There will be a course pre-test called AMS (Astronomy
Misconception Survey) AFTER you finish the warm up
– Please do your best. Won’t count as part of your grade. We
just want to know what you know coming into the course
• After these are done you will get a set of CPR and PRLQ
quizzes
– Instruction quizzes
– Practice Quizzes
• When these are done you will be able to get to the End-ofChapter Quizzes
– First one is Chapter 2 (no chapter 1 quiz)

for students (past, present and future) who want to
stay in touch with the course
• Learning about the Big Bang and Black Holes
Without the Math
• It’s not part of the course, but I try to post fun,
related things there periodically
– If you send me something fun (and appropriate)
I’ll post it for everyone
– If you send me something fun, but inappropriate,
I’ll say thank you and just enjoy privately

Learning to Write and Critique
• Each CPR Assignment has two parts (Call them Stage 1
and Stage 2)
1.You do your own writing and submit
2.You review and grade other papers (and your own)
• Why?
– Learn how to evaluate excellence and give feedback
(grade) papers to make them better
– Learn to better evaluate your own work to make it
excellent BEFORE you turn it in
• Want you to get good at writing and evaluating before
we get to the main paper assignments for this class

The “I hate CPR Club”
• Most students HATE CPR until they get good at it
• Many reasons:
– Takes practice to get good at the system
– Learning how to both be a good writer and be a good editor is
really difficult (and incredibly important) skill – Takes practice
– We require you follow the instructions
– You need to learn the standards we will be using in the class,
not your own, personal standards
• My advice: Don’t fight the system, blame it for being “unfair”,
or wish it were “better.” Just do what it takes to get good at it
• Don’t hesitate to ask for help
• If you are grumbling and neither I nor the TA have heard from
you to talk to you about it, then you get what you deserve
– Don’t pretend this is a way to get free grading by the
instructor… You’ll be wrong and it will just piss you off

Stage I and Stage II in CPR
Stage I: (Typically due before the first class of the Unit)
• Write 4 questions and turn them into CPR (online)
• Make sure to use HTML formatting (do a Preview to check)
– Use the <p> or <BR> lines after your paragraph or question.
Stage II: (Typically due before the following lecture)
• Three-Parts
1. Calibrations (learning to use the Rubrics)
• Read an example submission and use the grading rubric to assign
a score. Grade the three example submissions (get only one free
try to pass the grading rubric)
2. Reviews (Grade three other submitted submissions)
• Ignore that it says you have only 5 minutes for this. I have set
it so you can start the reviews right after you finish your
calibrations
3. Self-Assessment (Grade your own submission)
Note: You get a separate score for each of the 4 parts (text,
calibrations, Reviews and Self-Assessment)

Help Available for Stage I
• Submit a draft for feedback from the TA
– Submit on eCampus in “Rough Drafts
(Optional)”
• We also recommend going to the Writing
Center
– This is especially true for when we get to
the papers
• Most common problems:
– Not reading the instructions
– Not using HTML formatting (do a Preview
before

Topic 2: Going Big
Help Available for Stage II
• Stage II help:
– Each calibration is graded 0 or 100%.
– You only get 2 tries for each of the 3 calibrations
– Many students have trouble with the calibrations
because they do them RIGHT before they are due,
and do them too quickly (and then fail them)
• Our advice:
– Do them early and ask for help if you fail one the
first time
– Practice in eCampus quizzes to help you get good at
them

Unit 1 and Later Units
•
•
PLRQ Unit 1 in CPR is different than the others
– It is Pass/Revise
– You must pass ALL four parts separately, just a 70% overall score
is NOT good enough. You will need:
• >70% on the overall score
• >35/50 on the text portion of your paper
• >14/20 on the calibration portion
• >14/20 on the reviews
• >7/10 on the self-assessment
• Have done the proper HTML formatting in your submission
– If you don’t pass the first time, you will have to do a Revision
Assignment (all the parts) until you pass
– For some reason I got LOTS of emails about this.
Later units are just your combined score for all parts
– You can do a revision if you want to get a better grade
– We will average the two scores

Plan for Each Chapter
Example for Chapter 2:
• Before Lecture:
– Read Chapters 1-4 in BBBHNM (Unit 1)
– Do Stage 1 of PLRQ in CPR for Unit 1 (submit 4 questions)
• Do for next class
• During Lecture
– Listen & Ask Questions
– Take clicker and other quizzes
• After Lecture
– Finish Stage 2 of CPR for PLRQ for Unit 1
• Will be for the class after that
– If we finish Chapter 2, then take End-of-Chapter quiz 2 in
eCampus

Going Big – Chapter 2
• You have to get started
somewhere
• Start by looking at the various
things in the universe
– Go from sizes we know to the
VERY big
• After that we’ll do the very
small

The Very Big: Why Start Here?
• If we want to understand the universe
and where it comes from (and what’s
going to happen to it) we need to know:
1.What’s in it
2.What it’s made of
• Said differently, "What are we trying
to explain?”
– If we were detectives trying to
explain what happened, we’d need to
gather evidence: What’s the evidence
we can gather by looking at the
scene of the crime?

score on all of them
Good news:

PLRQ: Rubric Questions 1 & 2
1) For the first writer-submitted question: Is it obvious that the
question write has read the material? Do not choose No due to
a simple or basic question. Do not choose No if it appears the
writer is struggling with the concepts of the chapter. Choose
No if seems that the writer did not read the chapter. Choose
No if the writers question is already answered in the chapter.
Be careful not to say No if a SIMPLER question is answered in
the book.
2) For the first writer-submitted question: Is the question
relevant to the reading? If the question is about science or
borderline science fiction, that is ok. But if it is not about
relevant topics choose No. Choose No if the writers question
is already answered in the chapter. Be careful not to say No
if a SIMPLER question is answered in the book.

PLRQ: Rubric Questions 3-5
3)
4)
5)
For the first writer-submitted question: Is the question clear, well phrased,
thoughtful and not too speculative? Being well written is not enough. The
question must seem sincerely aimed at acquiring new information. Questions
like "What would happen if Einstein didn't come up with Relativity" is too
speculative to get a Yes. Choose No if the writers question is already
answered in the chapter. Be careful not to say No if a SIMPLER question is
answered in the book.
For the first writer-submitted question: Does the question reflect critical
thinking? If it is asking for a fact that might need to be determined by an
experiment, then you can give it a Yes. If this is a definition question, or is
fact-based question directly answered in the book, then select No. Be careful
not to say No if a SIMPLER question is answered in the book.
For the first writer-submitted question: Is the question asking for
information or clarification about an important point or asking for clarification
on an interesting new idea about a relevant topic? Any one is fine, but it does
have to be specific. For example, "I don't understand General Relativity,
please elaborate" is bad, but "Why is General Relativity needed for GPS to
work" is good. Choose No if the writers question is already answered in the
chapter. Be careful not to say No if a SIMPLER question is answered in the
book.
